Abstract
Advanced countries around the world are spurring the development of Unmanned Surface Vehicles (USVs) that can operate autonomously at marine environment. The key enabling technology for such USVs is the mission planning system (MPS) that can autonomously navigate through the harsh waters. The MPS not only has the functions for the navigation, but also has the capabilities, such as obstacle avoidance, malfunction corrections, dealing with unexpected events, return home functions, and many other eventualities that cannot be programmed in advance. The autonomy levels are increasingly moving higher and it is foreseeable that the trend will continue in the future. The main purpose of this paper is the analysis of the MPS onboard the USVs, in terms of the categories, functions, and technological details. Also, we analyze the case study of autonomous mission planning control systems in various fields and introduce the features that constitute the critical functionalities of the mission planning systems.
Highlights
According to the development of advanced science technology and along with the changes of increasingly complicated maritime environment, the level of autonomy required for Unmanned Surface Vehicles (USVs) is getting higher and higher
We looked into the most current mission planning system (MPS) that is being developed for the USV
We analyzed various cases of MPS systems related to the integrated mission planning that can plan and execute missions autonomously
Summary
According to the development of advanced science technology and along with the changes of increasingly complicated maritime environment, the level of autonomy required for USVs is getting higher and higher. USVs will be able to react to the abnormal conditions, system malfunctions, and re-plan the original plans, while making a judgement in accordance with the priorities within the mission goals [4] [5] [6] In this sense, the MPS can be the most important component of any USV systems, if the USVs should be intelligent and self-operating at waters that are far beyond the reach of remote human operators [7]. By examining those current and previously successful MPS, one can identify the critical elements and the operating principles of the mission planning system Such studies have not been adequately conducted in the past. We suggest the essential technological functions of integrated mission planning systems that are onboard the various autonomous mission planning platforms [8]
